1. The accuracy of rotary bearing gears is mainly to control the accuracy of transmission between gears in operation.
2. If the above design requirements are relatively high, then the accuracy of the rotary bearing gear should be set a little higher, and vice versa, a little lower.
3. If the precision of rotary bearing gear is set too high, the processing cost will rise and the comprehensive balance will be needed.
4. The accuracy of the commonly used gears can be as follows: 7FL, or 7-6-6GM.
5. There is no formula for calculating the accuracy of the revolving bearing gear, because it does not need to be calculated, and it is obtained by consulting the manual.
6. The determination of slewing bearing accuracy level is the result of engineer's comprehensive analysis. If the transmission requires precision, or high load, alternating load and so on, the accuracy level will be set higher.
7. The accuracy level of slewing bearing is 5, 6, 7, 8, 9 and 10, and the smaller the value, the higher the accuracy.
8. The deviation grade of slewing support (tooth thickness) is also the grade given by the designer under the specific working conditions. The precision transmission is higher, the mechanical transmission is lower, the closed transmission is higher, and the open transmission is lower.
9. The deviation grades of slewing support (tooth thickness) are C, D, E, F, G, H, J, K, L, M, N, P, R and S, with the largest gap in C and the smallest gap in S.
10. Whether it is the accuracy grade or the deviation grade of slewing support, the higher the setting, the higher the processing cost. After comprehensive analysis, a proper accuracy grade and deviation grade need to be given concretely.
